I will include both black controllers with the rechargeable battery packs(doesnt come with xbox out of box, paid extra for these)

Comes with all cables and wires and original wrapping and packaging(box is kinda beat up tho). The xbox is in mint condition and have used it for less than a year. It can still play backup games so you can make your won backups

I dont know, there probably is but im not gonna even start to try, something with getting a serial number from another xbox or something. Again, this xbox is intended for someone who just plays offline and doesnt wanna pay xbox 50/year for the gold membership
